LUBRICATING MEANS FOR- JOURNAL BOXES.

Application filed August 5, 1922. Serial No. 579,903.

To all whom it may concern:

Be it known that I, BERT H. Bnosn, a citizen of the United States, residing at Johnsonburg, in the county of Elk and State of Pennsylvania, have invented certain new and useful Improvements in Lubricating Means for Journal Boxes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to journal boxes, and more particularly to lubricating means for journal boxes. 7

It is an object of the invention to provide means of this character wherein the usual oil swab or packing is eliminated, and the journal of the axle immersed in a quantity of lubricant.

It is another object of the invention to provide means of this character substantially in the form of a receptacle capable of being applied and removed from the journal box, the receptacle being of a charactor to hold a small quantity of oil and yet permit the major portion of the journal of an axle to be immersed in the oil.

It is also an object of the invention to provide means of this character in the form of a receptacle constructed to receive the journal of the axle, means being provided for spacing the receptacle from the journal box, the receptacle substantially embracing the greater portion of the journal of the axle.

It is a further object of the invention to provide lubricating means of this character in the form of a receptacle adapted to receive the major portion of the journal of an axle, to permit said portion to be immersed in oil, the receptacle being provided with a hinged lid to facilitate filling of the receptacle with oil and to protect the oil and prevent splashing thereof. 7

It is astill further object of the invention to provide means of this character including a receptaclehaving one end open for the reception of the journal of an axle and provided with means to prevent the escape of lubricant through said end.

With these and other objects in view, the

invention consists in the improved construction andarrangement of parts to be hereinafter more particularly described, fully claimed and illustrated in the accompanying drawings, .in Which:-

Figure 1 is a longitudinal sectional view of a journal box showing the invention ap plied;

Figure 2 is a top plan and sectional view of the journal box with the invention applied;

Figure 3 is a section taken on the line 33 of Figure 1; and

Figure 4 is alongitudinal sectional view of the lubricant receptacle.

Referring to the drawings, 5 designates a conventional form of journal box including a bottom 6, a front wall 7 and a rear wall 8, said rear wall being provided with the usual journal opening?) through which the journal A of the axle B passes. The journal box is provided with the usual hinged cover 10. The structure above described is well known, and forms no part of the invention.

The means previously proposed for lubricating the journals of car axles is unsatisfactory, in view of the frequency of hot boxes, caused by friction of the journal and drying of the lubricant packing, This disadvantage is overcome by the novel provision of an oil cellar in the form of a receptacle 11, said receptacle including side walls 12, a bottom 13, and a front wall 14:. The front wall is curved in accordance with the curvature of the journal box and is also extended inwardly so as to direct the lubricant toward the journal of the axle. The side walls 12 have their rear end portions enlarged or thickened as at 15 and tapered toward the center of the receptacle, so as to decrease the distance between said walls at the ,rear end of said receptacle. The extremity of the enlarged portion of each side wall is reduced to provide a recess 16, said recess extendingthrough the rear end of the receptacle, the purpose of which will be hereinafter described. The bottom 13 of the receptacle has its rear end portion enlarged or thickened as at 17 and tapered toward the center of the receptacle, similar to the enlarged or thickened portions of the sides. It is of course obvious that the enlarged portions of the sides and bottom merge to substantially provide a rounded bottom, the bottom, similar to the side walls, having the extremity of its enlarged portion reduced to provide a recess 18, said recess merging with the recesses 16 of the walls to provide a substantially semi-circular recess at the rear end of the receptacle. By this means the rear end is rendered relatively narrow so as to retain the oil within the receptacle and at the same time prevent the escape of the oil.

Depending from the bottom of the receptacle are legs 19, said legs being disposed at the front, central and rear portions of the receptacle, so as to hold the receptacle in spaced relation to thebottom face of the journal box and also closely adjacent the journal A. It will be noted that the receptacle is slightly larger than the journal so as to hold a-small quantity of oil and yet permit the oil to rise to a level above the center of the journal. By this means only a small portion of the journal projects above the receptacle, the rest of the journal being entirely immersed in lubricant.

To facilitate the application of oil to the receptacle, a plate 20 is hinged to the upper edge of the front wall l lof'the receptacle. Said plate is adapted to extend over the edge of the opening in the front wall to serve as a rest for the spout of a supply oil can when the device isbeing filled. This cover is also intended to be swung inwardly when the, lid 10 of the journal box is closed, soas to cover the oil in the front end of the receptacle, and thereby exclude dust. It also preventssplashing caused by the rotary movement of the journal.

It is of course obvious that the receptacle is substantially semi-circular in cross section, so as to conform to the curvature of the journal A of theaXle B. The large semi-'circular recess, formed through the cooperation of the recesses 16 and 1 8', is intended to receive a stripof graphite 21 and a strip of wool or hemp packing 22,- the packing being adapted to engage the inner shoulder C of the journal to' not only lubricate the same, but to also prevent'the lubri cant in the receptacle from escaping through the opening 9* of the journal box. Furthermora'the packing is constantly sup plied with oil which is directed to the packing from the enlarged" portions of the receptacle. The packing 22, however, is relatively small so that there is no possibility of friction being generated to an extent sufficient to cause a hot box.

It will be noted that the front feet of the receptacle are disposed closely adjacent the curved bottom of the journal box so that there is no possibility of'the receptacle moving toward" the front wall of the journal box. The curved portion of the journal ho prevents this. By spacing the receptacle from the bottom and front wall the space between. the; receptacle and the journal box is freeto receive air which assists in preventing overheating. In order to permit the removal of the receptacle when necessary, the front wall 14 of the receptacle is providedwith a bail 23,- the ends of said A is partially immersed in oil without requi-ring a large quantity of oilfor this purpose, in view of the size of the receptacle. Consequently, the receptacle does not require the use of pacl'rin'g for engagement with the major portion of the journal-,but only a small strip of packingat each endof the oil cellar to prevent-leaking of the oil and at the same time lubricate the inner shoulder of the journal. All of tl'iese features are possessed bya device which isc'ompact in form and simple in construction and which may be easily applied.

That is claimed is 7 1. Lubricating means: for journ'al boxes,
